(54) | Thermal imaging device |
(57) A pyroelectric film 21 has a pattern of inter-connected electrodes 22 formed on one
major surface, and a pattern of discrete electrodes 24 formed on the other major surface.
Each discrete electrode 24 has an aperture 31 in which is formed a respective electrically
conductive pad 23. The film 21 is supported by pillars 26 connected to the pads 23,
the pillars also providing a path for electrical signals between the pads 23 and a
signal processing means 28. Each discrete electrode 24 is connected to a respective
pad 23 by a respective strip of electrically conductive material. |
